Heavy-duty security hinges are specialized hinges designed for use in high-security applications where doors need to be able to withstand significant force or impact without compromising the security of the space. These hinges are commonly used in prisons, detention centers, and other secure facilities.
Heavy-duty security hinges are typically made of high-strength materials such as steel or stainless steel, and are designed to securely hold the weight of heavy doors while also providing a high level of tamper resistance. They are often designed with a non-removable pin to prevent the hinge from being easily removed, and may also include features such as hardened steel bearings to prevent the hinge from being forced open.
Some common features of heavy-duty security hinges include multiple mounting holes for added stability, adjustable tension settings for a proper fit, and compatibility with a wide range of door sizes and styles. Many manufacturers also offer hinges with tamper-proof fasteners to prevent unauthorized removal, as well as corrosion-resistant coatings for use in harsh environments. Some heavy-duty security hinges may also be designed with ball bearings or other mechanisms to reduce friction and ensure smooth operation even under heavy loads.
